Separation surface A between 01 and the satellite separation unit main body 02 on the rocket side
A bracket 4 is screwed to the outer periphery of the satellite separation unit main body 02 immediately below the bracket. A pin bolt 6 penetrates the bracket 4 almost perpendicularly to the axis of the satellite separation unit main body 02. The hook 3 is pivotally supported in a rotatable manner. The hook 3 has a hook engaging seat 3a whose outer surface near the separation surface A, that is, the outer surface farther from the axis of the satellite separation unit main body 02 is a seat surface substantially perpendicular to the axis.
And a latch engagement seat 2a of a latch arm 2 described later.
And is configured to engage with. The other end of the hook 3 has a cable receiver 3b, which is a depression for locking the cable 10 outside the machine axis, so that the cable 3 does not slip when the cable 10 is hooked. At a position closer to the separation surface A than the hook 3, a latch arm 2 pivotally supported by a bracket 4 with a pin bolt 5 substantially parallel to the pin bolt 6 is provided. Latch engagement seat engageable with hook engagement seat 3a of hook 3

The other end of the latch arm 2 is bent toward the satellite 01 and holds the satellite 01 almost parallel to the aircraft axis via an adjustment bolt 2b provided at the tip of the latch arm 2 so that the satellite 01 contacts the satellite separation unit main body 02 on the rocket side. It is fixed in contact. One end of the torsion spring 8 to the pin bolts 5 as shown as the axis for the latch arm 2 is hooked, the other end direction of the arrow T 1 the latching arm 2 have been hooked to the bracket 4, i.e., the adjustment bolt It works so that the end provided with 2b is always rotated in a direction to separate from the satellite 01. Further, the hook 3 hooked one end of the torsion spring 9 around an axis of the pin bolt 6 and the other end faces of the bracket 4 to have hooked hook 3 the arrow T 2, i.e., the latch of the latch arms 2 It works in a direction to always release the hook engagement seat 3a from the engagement seat 2a. The function of the torsion spring 9 is restricted by the tensile force of the cable 10 hooked on the cable receiver 3b of the hook 3.

With the above configuration, the hook 3 restrains the rotation of the latch arm 2, and the latch arm 2 is connected to the satellite 01 via the adjustment bolt 2b.
And the satellite separation unit main body 02 are restricted from being separated. As shown in FIG. 1, the latch device 1 constructed as described above restrains the satellite 01 and the satellite separation unit main body 02 on the rocket side at four places on the periphery of the satellite separation unit main body 02 by one cable 10 as shown in FIG. Even if the coupling bolt / separation nut 03 operates, the cable
As long as the satellite 10 is not cut as described below, the satellite 01 and the satellite separation unit main body 02 remain fixed to each other and are not separated.

When the satellite 01 is fixed by the latch device 1, the latch arm 2 at the position shown by the two-dot chain line in FIG. 2 (b) is raised against the torque of the torsion spring 8 at the position shown by the solid line in the drawing. Similarly, the hook 3 at the position indicated by the two-dot chain line is rotated counterclockwise against the torque of the torsion spring 9 so that the hook engaging seat 3a is engaged with the latch engaging seat 2a and is restrained by the cable 10. When the hook 3 is rotated counterclockwise to engage the latch engagement seat 2a, the hook engagement seat is attached to the latch engagement seat 2a.
A stopper pin 7 is provided on the bracket 4 so that 3a does not overlap beyond the precise range, so that the extra counterclockwise rotation of the hook 3 is stopped. When the installation of the cable 10 is completed, turn the adjustment bolt 2b and turn the satellite 01
Is adjusted so that the four latching devices 1 hold down the satellite 01 evenly.

When the fuel of the rocket launched with the satellite 01 is exhausted, the rocket that has been used up is a satellite with the satellite separation unit main body 02
Separated from 01. Therefore, first, a pyrotechnic or the like (not shown) of the connection bolt / separation nut 03 is operated to release the connection of the connection bolt. After all four connection bolts are released, a cable cutter (not shown) is operated to cut the cable 10. Then, the hooks 3 of the four latch devices 1 are simultaneously released from the restraint and are rotated by the torsion spring 9 to the position shown by the two-dot chain line in FIG. It comes off from the engagement seat 2a. Then, the latch arm 2 is rotated to the position indicated by the two-dot chain line in FIG. 3 by the torque of the torsion spring 8, and all the satellites 01 are released from the restraint. Next, the satellite separation unit main body 02 quietly separates from the satellite 01 by retro thrust together with the rocket.

The processes from the operation of the coupling bolt / separation nut 03 to the operation of the separation device of the present embodiment are all performed in sequence in a preset order. Thus, for example, it is unlikely that the cable 10 will be cut without all of the connecting bolts / separation nuts having been fully actuated due to the slow deflagration rate of the pyrotechnic.

As described above, according to the present embodiment, the satellite 01 and the satellite separation unit main body 02 are not immediately separated by the operation of the coupling bolt / separation nut 03. Since the latch device 1 releases the satellite 01 at four places simultaneously by the disconnection, the satellite 01 is released and released when the satellite 01 is released.
Non-uniform forces, vibrations, shocks, etc., which affect the posture of the robot, do not occur at all, and the separation is achieved very naturally.
Therefore, it is possible to obtain an ideal satellite separation apparatus which does not cause the satellite 01 to have an attitude error at the time of separation and unnecessary rolling.

Although the cable cutter (not shown) is used to release the cable 10 in the above-described embodiment, the hook 3 is connected to the release position (the position indicated by the two-dot chain line) for all of the plurality of latch devices 1. If it is possible to provide a stroke, it may be possible to use not only cutting but also, for example, appropriate cable loosening means or other appropriate means. Further, the use of the latch device 1 is not limited to four places.

The present invention has the following effects because it is configured as described above. That is, it is possible to prevent a delay in operation of the separation device and a posture error (disturbance) due to impulsive imbalance that occur when the satellite and the rocket are separated. Further, even if disturbance from the satellite acts on the latch arm while the satellite is held, no rotational force acts on the hook body, so that no extra tension acts on the cable. That is, because of the so-called irreversible structure, there is no concern that the reliability of the device is impaired by disturbance.

1. A bracket attached to a rocket side outer periphery near a separation plane between a satellite and a rocket of an artificial satellite rocket,
The bracket is pivotally supported in a seesaw shape with a pin axis substantially perpendicular to the rocket's machine axis, and has a seating surface that is substantially perpendicular to the machine axis at the end nearer to the separation surface as viewed from the machine axis. And a hook body having a cable engaging portion on the other end side outside the machine axis, and the bracket being rotated by a pin axis substantially parallel to the pin axis at a position closer to the separation surface than the hook body. A latch arm that is pivotally supported and has a seat surface engageable with the seat surface of the hook body and has the other end bent toward the satellite side to fix the satellite in contact with the rocket; A spring that works in a direction to always keep the other end of the latch arm away from the satellite, a spring that works in a direction to always release the hook from engagement with the latch arm, and engages the hook with its cable locking portion. To the rocket side Satellite separation apparatus characterized by comprising comprises a cable which is provided releasably its attractiveness as desired by means.
